To all whom it may concern.-

HENRY KOLLING, of Arlington Heights, in

the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Thrashing-Machines, of which the following is aclear and exact description, reference being bad to the accompanyingdrawings.

Our invention relates to certain improvements inthrashing-machines, asfully hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspective view of the right-hand sideof the machine. Fig. 2 is an elevation of the left-hand side. Figs. 3and 4 are an elevation and section of the rattle-rack mechanism. Fig. 5is a longitudinal section of the machine. Fig. 6 is a cross-section ofthe beating-cylinder. Fig. 7 shows the vertical adjustment of thepicker. Fig. 8 is the apron-stretching device. Fig. 9

.is a perspective view of one of the blast-regulating boards with itsadjusting device. Fig. 10 is a plan of the main driving-shafts. Fig. 11is a cross-section of the machine through the center of thethrashing-cylinder. Figs. 12 and 13 show the inside view andcross-section of the concave adjusting device; and Fig. 14 is across-section of the riddle-shoe.

A is the frame and easing, of ordinary con- B is the thrashing-cylinder,armed with teeth in the usual manner. The ends of said cylinder areprovided with circumferential grooves or flanges b, and circular platesbl are secured against the'sides of the casing, and extend entirelyaround the cylinder, the inside edges projecting into said grooves b, sothat no straw or chaff can work in between said cylinder and easing,thereby obviating any extra friction and delay.

The cylinder B is mounted upon a shaft, B, placed in suitable boxes ofthe frame, and having driving-pulleys b and b on its extreme ends.

The chute 0, onto which the grain in the straw is fed, is a loose board,hinged at its bottom edge 0 to the front edge of the con-v cave D, armedwith teeth in the usual manner. The rear end of said concave is pivotedupon a fixed rod, 0. d are slotted legs, pendpart of the concave. E is ashaft, placed in suitable hearings in the frame, and having two cranks,e, the end pins of which enter the slots in legs (1. One end of saidshaft'E projects through the frame, where'it has a ratchet-wheel, E, to.be locked by a paw1, e pivoted to the frame, and a hand-lever, 6 By thisarrangement the width of the throat between cylinder and concave can beregulated to suit the different kinds and qualities'of grain, and theoperator canrelieve the cylinder momentarily if by irregular'feed itshould get choked. V

The shafts F and F carry small pulleys, which have each a projectingflange, and drive an endless apron, placed on an incline, to convey thegrain and straw as it comes fromthe thrashing-cylinder. The shaft F ispivoted in fixed boxes, while the shaft F rotates in the end ofratchet-bars f, being longitudinally slotted. These bars f are placedinto mortises of the frame-stanchions, being retained therein each by apin passed through theslot and adjustably secured by a turn-pawl, f,pivoted against the stanchion of the frame, and matching with any one ofthe ratchet teeth of the bars f. This arrangement furnishes a simple andeffective device for tightening the apron. I

G is the beating-cylinder. It consists of a shaft, g, to'which areattached two heads, provided with sockets for the ends of thebeater-bars g This beater is to lighten up the straw as it comes fromthe thrashing-cylinder, to allow the grain .to fall out, and. as forsome kinds of seed its use is not required, our improvement consists inconstructing the heads 9 each in two halves, cut through the centerline, secured together by bolts, as shown in Fig. 6, so that the beatercan be removed from its shaft without taking the latter out of itsbearings and oi the frame.

The picker H, which is to shake the straw while passingover it, isjournaled in boxes it, (see Fig. 7,) having a slotted plate, h, which,by a single bolt, each passed through the slot of said plate, aresecured to the stanchion's of the frame in such a manner that they allowa ready vertical adjustment or entire removal, as in thrashing fiaxseed,when said picker is ing from under the front end, and forming notwanted.

The rattlerack consists of an endless slotted straw-carrier, placed onan incline, and receiving a shaking motion from an oscillating doublecrank-shaft placed under it. Its

object is to separate the grain and failings from the straw, whichlatter is carried off and delivered upon the stack, while the formerdrops through upon the inclined bottom of the casing, whence it slidesdown and dis charges upon the riddle-shoe.

I is a shaft, receiving motion by a pulley on its end. It is journaledin two sliding boxes, i, each having an extension rack-bar, which isarranged to have a longitudinal sliding motion in a box, 2', bolted uponeach side of a machine, in which it is moved forward and backward bymeans of a pinion, 70, each hidden inside of said boxes 2', and whichmatch into the teeth of the rack'bar. Both these pinions k are securedupon a common shaft,

'K, pivoted into the frame of the machine, and

having a squared end for the attachment ofa crank and a ratchet-wheel, Klocked by a pawl, K which latter is pivoted to the frame. To one end ofthe shaft is also secured acrankplate, 1 which, by a rod, 1 is connectedto bell-crank 1, being secured upon the end of shaft L, with doublecranks l, carrying rollers on their extreme ends, which, while saidshaft is oscillated, will alternately strike against and raise therattle-rack. The ends of shaft L are pivoted in about the center of barL, which is connected at one end to the end of the bar 2', while itsopposite end is coupled to the ends of shaft M, journaled in boxes m,sliding in guide-bars m, which are secured to the inside walls of thecasing in an oblique direction. The casing-walls are mortised tocorrespond with the sliding motion of shafts L and M. The shafts I and Mhave each two small pulleys, over which the rattlerack is stretched.

By turning the shaft K the shafts I, L, and M are moved forward andbackward. The shafts L and M thereby, in following the oblique directionof the guides m, are brought to a more or less elevated position, so asto suit the different kinds and qualities of grain which may be thrashedwith or without the picker H-as, for example, in thrashing flaxseed, thepicker H is removed entirely, and the rattle-rack is brought forward toits most elevated position.

N is the riddle-shoe, having an inclined bot tom toward the front of themachine, where it is open. It is hung at the front or inner end upon apivot in the usual way, and at the rear it is suspended by two hangers,which allow to it a shaking motion. Said riddleshoe N on its top has agrating, n, composed of a'series of bars placed longitudinally andparallel to each other, and below this is the screen n. Any strawsdelivered with the grain and chaff will be retained by the grating, andwill be blown over the shoe without first dropping upon the screen,where a stronger blast would be required for removing them.

The chad, dust, and other refuse are separated by the sifter, and bymeans of the fan-blast are discharged over the end of the shoe, whilethe clean grain only will slide down in the bottom of the shoe into atrough, O, delivering the same at both sides of the machine. Thetailings and unthrashed heads will collect in the trough 0, thencedischarging into the elevator.

The fan P is arranged in the usual manner. It is driven by a belt at oneside of the machine, while to the opposite end of its shaft is secured abevel-gear, matching with a similar gear-wheel on shaft 10, journaledlongitudinally to the side of the machine, and having a crank, 19, atits ends, which, by means of a connecting-rod, is coupled to the bottomof the shoe N, for transmitting a shaking motion to said shoe.

The blast of the fan P is regulated and directed by two wing-boards, Qand Q. The lower one, Q, is hinged to the lower end of the opening inthe fan-casing, its outward end resting upon two arms, q, secured to ashaft, g and adjusted by a quadrant, q, fixed to the end of the shaft,and adjustably secured against the outside of the frame or casing A bymeans of a leg-screw in the said frame, all arranged as shown in Fig. 9.The upper wingboard Q is pivoted into the frame A, one of its end pivotshaving a quadrant, q, and being adjustably secured similar to board Q.

The elevator B, into which the unthrashed heads are discharged, hoistsand spouts the same under the thrashing-cylinder again, is constructedin the usual manner, with the exceptance that the lid r is hinged on itstop end, so as to open upward, thereby saving the hinges, which, wherethe lid is arranged to open to the side, are frequently broken.

The spout S is suspended to the head of the elevator by having twoprojecting side studs, 8, inserted into staples s of the elevator-head.Its lower end rests upon a roller, T, pivoted to the top of the machine.A shaking motion is transmitted to said spout from a crank, t, securedto the end of the top elevator-shaft, and connected to the side of thespout by a rod, t.

The main driving-shafts U and V are placed in suitable hearings in theframe of the machine, and right-angularly to each other, being gearedtogether by miter-wheels u v. The extreme ends of these shafts,extending beyond the bearings, are squared for coupling thetumbling-shaft, so that power may be attached to either side or to thefront of the machine. The pulleys u and u are for driving thethrashing-cylinder, while pulley 21, is for driving the balance of themachinery.

The door W, which opens the side of the frame at the riddle-shoe, ismade to slide longitudinally in the said frame, which we prefer tohanging it with hinges.

- All the pulleys arranged for carrying the apron and rattle-rack, aswell as the beatingcylinder and picker, we intend to have guardedagainst the admission of straw or chaff, in a similar manner, as shownand described for the thrashing-cylinder.

What we claim as'onr invention, and desire to secure by Letters Patent,is-

1. In a thrashing-machine, the combination of the thrashing-cylinder B,provided with grooves at its ends, with guard-plates b, extendingentirely around said cylinder, and projecting into the grooves in thecylinder, substantially as described and shown.

2. The rattle-rack shafts I and M and the shaker-shaft L, all arrangedin sliding boxes in frame A, and connected so as to be simultaneouslyadjustable in an oblique direction, substantially as and for the purposedescribed and shown.

3. The rattle-rack shaking-shaft L, journaled in adjustable bearing-barsL, and oscillated from the rattle-rack shaft by arm I and connecting-rodI substantially as described and shown.

4. The rattle-rack shaft I, journaled in the boxes 2', adjustable inboxes '6, in combination with the shaft M, journaled in boxes m, whichslide in oblique guides m, the bearings of the shafts I and M beingcoupled by a bar, L, all constructed and arranged substantially asdescribed and shown.
